Published: October 23, 2008Last spring, Jeremy Sapienza, a 28-year-old Web editor, and his partner bought a two-story house on a rough block of Central Avenue in Bushwick, Brooklyn. Like most urban pioneers, they have been renovating as funds allow.

They couldn’t afford to redo the facade, though, which Mr. Sapienza described disdainfully as “flat stucco painted Pepto-Bismol pink.” So this summer they hired an artist named Erik Burke to cover it with a mural.
